• Can anyone recommend a .Net XML Serialization library?

  - by James

  Can anyone recommend a .Net XML Serialization library (ideally open source). I am looking for a robust XML serialization library that I can throw any object at, which will produce a human readable XML representation of the public properties for logging purposes. I never need to be able to deserialize. XmlSerializer's requirement of an object having a parameter constructor is too restrictive for what I want. DataContractSerializer does not give enough control over the output (which is not particularly human-readable). Any recommendations appreciated! Thanks

• convert from physical path to virtual path

  - by user710502

  I have this function that gets the fileData as a byte array and a file path. The error I am getting is when it tries to set the fileInfo in the code bewlo. It says 'Physical Path given, Virtual Path expected' public override void WriteBinaryStorage(byte[] fileData, string filePath) { try { // Create directory if not exists. System.IO.FileInfo fileInfo = new System.IO.FileInfo(System.Web.HttpContext.Current.Server.MapPath(filePath)); //when it gets to this line the error is caught if (!fileInfo.Directory.Exists) { fileInfo.Directory.Create(); } // Write the binary content. System.IO.File.WriteAllBytes(System.Web.HttpContext.Current.Server.MapPath(filePath), fileData); } catch (Exception) { throw; } } When debugging it, is providing the filePath as "E:\\WEBS\\webapp\\default\\images\\mains\\myimage.jpg" . And the error message is 'E:/WEBS/webapp/default/images/mains/myimage.jpg' is a physical path, but a virtual path was expected. Also, what it is triggering this to happen is the following call properties.ResizeImage(imageName, Configurations.ConfigSettings.MaxImageSize, Server.MapPath(Configurations.EnvironmentConfig.LargeImagePath));

• ORMs and Constructors

  - by Harper Shelby

  I'm looking over .NET ORM implementations, and I have a major burning question - are there any .NET ORM implemenations that don't require public properties for every field in the database? When I see examples like this, a little bell goes off in my head. I firmly believe in encapsulation, and being forced to open the kimono of my objects just to make them work nicely with persistence frameworks gives me the heebie-jeebies. Is this sort of accessibility required in all ORMs out there? If not, please point me to examples of those that don't need it!

• Eclipse, Android ndk, source files, and library project dependencies

  - by Android Noob

  In Microsoft Visual Studio 2010, it is possible to create a Solution with multiple projects and set dependencies between projects. I'm trying to figure out if the same thing can be done using Eclipse via the NDK. More specifically, I want to know if it is possible to create C source files in an ordinary Android project that can reference C header files in an Android library project. For example: Android library project: Sockets Ordinary Android project: Socket_Server Sockets contains all the C header/source files that are needed to do socket I/O. Socket_Server contains test code that makes calls to the functions that are defined in Sockets library project. This test code requires a header file that contains the function declaration of all API calls. I already set the library dependencies between the projects via: Properties > Android > Library > Add

• clearcase option for view movement from one host path to another

  - by wrapperm

  Hi all, I have created a clearcase dynamic view for my development by name "view1". I have mistakenly selected the view storage location as a local PC in my network, that was made sharable by the PC owner. I was suppose to select the view storage location to be a server. Now, the issue is that I have done lot of development with the view that I have created and have plenty of view DO's and view private files in it. So I'm ruling out the option of deleting the view from the PC local storage (host path) and then creating another view in the server with the same config spec. Please, let me know if there is any method of editing the view properties (or doing something else) by which I could be able to move the view to the server (with all the DO's and view private files retained) Thanks in advance, Rahamath

• Interesting AS3 hash situation. Is it really using strict equality as the documentation says?

  - by Triynko

  AS3 Code: import flash.utils.Dictionary; var num1:Number = Number.NaN; var num2:Number = Math.sqrt(-1); var dic:Dictionary = new Dictionary( true ); trace(num1); //NaN trace(num2); //NaN dic[num1] = "A"; trace( num1 == num2 ); //false trace( num1 === num2 ); //false trace( dic[num1] ); //A trace( dic[num2] ); //A Concerning the key comparison method... "The Dictionary class lets you create a dynamic collection of properties, which uses strict equality (===) for key comparison. When an object is used as a key, the object's identity is used to look up the object, and not the value returned from calling toString() on it." If Dictionary uses strict equality, as the documentation states, then how is it that num1 === num2 is false, and yet dic[num1] resolves to the same hash slot as dic[num2]?

• Anchors requiring multiple clicks to fire

  - by novaurora

  'This is bizarre bug. I have CSS3 anchors/buttons, which I've continued to strip properties out of, that sometimes require multiple clicks to fire. I've never seen anything like it. http://votizen.com Sometimes it happens, sometimes it doesn't. So it's very tough to pin down. If anyone is interested in helping me, check out the page and the source code on the large 'Sign in with Facebook' or 'Sign in with Twitter' buttons. Thank you!

• Why is the binding icon not visible in blend?

  - by Ankit Rathod

  Hello, Why is the binding icon (a small gray icon) not visible in blend for some properties even though they are DependencyProperties? For eg. I dragged a button on my page and dragged a textbox. I want to bind button's content property to textbox's text property. But i can't find the Binding icon in Blend. I know if i type the binding syntax in code it will work just fine. But why is that icon missing? Thanks in advance :)

• Looking for a C# code parser

  - by Blindy

  I'm looking for a set of classes (preferably in the .net framework) that will parse C# code and return a list of functions with parameters, classes with their methods, properties etc. Ideally it would provide all that's needed to build my own intellisense. I have a feeling something like this should be in the .net framework, given all the reflection stuff they offer, but if not then an open source alternative is good enough. What I'm trying to build is basically something like Snippet Compiler, but with a twist. I'm trying to figure out how to get the code dom first. I tried googling for this but I'm not sure what the correct term for this is so I came up empty.

  Hi Everyone! I am using Flex 4 Spark Components for this one. I have a custom component that is larger than a certain container, and I need it to be centered in that container.

• Django adminsite customize search_fields query

  - by dArignac

  Howdy! In the django admin you can set the search_fields for the ModelAdmin to be able to search over the properties given there. My model class has a property that is not a real model property, means it is not within the database table. The property relates to another database table that is not tied to the current model through relations. But I want to be able to search over it, so I have to somehow customize the query the admin site creates to do the filtering when the search field was filled - is this possible and if, how? I can query the database table of my custom property and it then returns the ids of the model classes fitting the search. This then, as I said, has to flow into the admin site search query. Thanks!

But how to put it all together? Regards!

• How can I enable/disable network connection options programmatically

  - by nikie

  When I open the properties on a network connnection on windows, I see this dialog: In this dialog, in the check-listbox I can enable or disable options like "File or printer sharing", "client for microsoft networks" or network filter drivers. My question is: How can I enable/disable these options programatically? I didn't find anything that looks like this in the WMI documentation and I couldn't find any other Win32 API for this. I would prefer a C Win32 API or WMI interface, but a solution using any programming language is welcome. The question is language-agnostic.

• how to populate an entity you have extended in the Entity Framework?

  - by user169867

  I have an entity in my EDMX that I've extended with a few fields in a partial class like this: public partial class Employee { public string JobName {get;set;} } These properties are for display only. In the above example say the entity has a JobTypeID property. I wish JobName to be populated w/ the name that belongs to that JobTypeID. Is there anyway to query the employee record in EF including the value for the JobName property w/o explicity assigning each field using select()? The reason I ask is that there are a lot of fields in the Employee entity so I'd like to be able to take advantage of something like: ctx.Employees.Where(e=>e.EmployeeID==employeeID).Single() ...add somehow fill in JobName too Is this possible?

• Other SecurityManager implementations available?

  - by mhaller

  Is there any other implementation (e.g. in an OSS project) of a Java SecurityManager available which has more features than the one in the JDK? I'm looking for features like configurable at runtime policies updateable at runtime, read from other data sources than a security.policy file Thread-aware, e.g. different policies per Thread Higher-level policies, e.g. "Disable network functions, but allow JDBC traffic" Common predefined policies, e.g. "Allow read-access to usual system properties like file.encoding or line.separator, but disallow read-access to user.home" Monitoring and audit trace logging, e.g. "Log all file access, log all network access going NOT to knownhost.example.org" Blocking jobs "requesting" a permission until an administrator grants permission, letting the thread/job continue ... I'm pretty sure that application servers (at least the commercial ones) have their own SecurityManager implementation or at least their own policy configuration. I'm wondering if there is any free project with similar requirements.

• Catch access to undefined property in JavaScript

  - by avri

  The Spider-Monkey JavaScript engine implements the noSuchMethod callback function for JavaScript Objects. This function is called whenever JavaScript tries to execute an undefined method of an Object. I would like to set a callback function to an Object that will be called whenever an undefined property in the Object is accessed or assigned to. I haven't found a noSuchProperty function implemented for JavaScript Objects and I am curios if there is any workaround that will achieve the same result. Consider the following code: var a = {}; a.__defineGetter__("bla", function(){alert(1);return 2;}); alert(a.bla); It is equivalent to [alert(1);alert(2)] - even though a.bla is undefined. I would like to achieve the same result but to unknown properties (i.e. without knowing in advance that a."bla" will be the property accessed)

• Is it possible to have a Shared/Static Dependency Property?

  - by Matt H.

  [using VB.NET, but I can easily read C# code in responses] I have a class called QuestionClipboard with ALL shared methods/properties. I previously had a QuesitonClipboard.doesClipboardHaveContent function that returned true/false if there was a Object on my 'clipboard'. I'd prefer to implement a Dependency Property so I can allow this true/false value to participate in data binding. The "GetValue(dp as DependencyProperty)" method requires an object instance, which would mean that my Property CAN'T be shared! Here is what the code would look like in my perfect world... Of course, the word "Shared" before the property declaration renders this code useless. Private Shared clipboardHasContentPropertyKey As DependencyPropertyKey = DependencyProperty.RegisterReadOnly("clipboardHasContent", GetType(Boolean), GetType(QuestionClipboard), _ New PropertyMetadata(False, Nothing, New CoerceValueCallback(AddressOf coerceClipboardHasContent))) Private Shared clipboardHasContentProperty As DependencyProperty = clipboardHasContentPropertyKey.DependencyProperty Public SHARED Property clipboardHasContent As Boolean Get Return GetValue(clipboardHasContentProperty) End Get Set(ByVal value As Boolean) SetValue(value) End Set End Property

• ASP.Net: User control with content area, it's clearly possible but I need some details.

  - by bert

  I have seen two suggestions for my original question about whether it is possible to define a content area inside a user control and there are some helpful suggestions i.e. http://stackoverflow.com/questions/1971498/passing-in-content-to-asp-net-user-control and http://stackoverflow.com/questions/1912283/asp-net-user-control-inner-content Now, I like the theory of the latter better than the former just for aesthetic reasons. It seems to make more sense to me but the example given uses two variables content and templateContent that the answerer has not defined in their example code. Without these details I have found that the example does not work. I guess they are properties of the control? Or some such? The former example seems workable but I'd prefer to go with the latter if someone could fill in the blanks for me. Thanks.

• Using image resource in XAML markup?

  - by Jeff Dahmer

  I'm trying to add little icons to my tabs in WPF but having trouble with how to set up the binding. <TabItem.Header> <StackPanel Orientation="Horizontal"> <Image Source="{Binding Source=prop:Resources.eye}" /> <Label VerticalAlignment="Center">Header</Label> </StackPanel> </TabItem.Header> The xmlns:prop is set up for the local project's Properties, I am pulling other values from it elsewhere so I know that the namespace works. The markup above compiles fine BUT I don't see the eye image in the tab. Also, is there any way to set this up into a template? I'm fairly new to XAML/WPF and each tab will have its own image...

• EntityFramework WCF issue

  - by Andres Blanco

  Right now i'm doing some tests involving entityFramework and WCF. As I understand, the EntityObjects generated are DataContracts and so, they can be serialized to the client. In my example I have a "Country" entity wich has 1 "Currency" as a property, when I get a Country and try to send it to the client, it throws an exception saying the data cant be written. But, the thing is, if I Get a Currency (which has a collection of Countries) and dont load its countries, it does work. The client gets all the entities. So, as a summary: - I have an entity with another entity as a property and cant be serialized. - I have another entity with an empty list of properties and it is successfully serialized. Any ideas on how to make it work?

• Pointers, links, object and reference count

  - by EugeneP

  String a = "a"; // allocate memory and write address of a memory block to a variable String b = "b"; // in a and b hold addresses b = a; // copy a address into b. // Now what? b value is completely lost and will be garbage collected //* next step a = null; // now a does not hold a valid address to any data, // still data of a object exist somewhere, yet we cannot get access to it. Correct me if there's a mistake somewhere in my reflexions. My question is: suppose anInstance object of type Instance has a property ' surname ' anInstance.getSurname() returns "MySurname". now String s = anInstance.getSurname(); anInstance = null; question is - is it true that getSurname value, namely MySurname will not be garbage collected because and only because it has active reference counter 0, and if other properties of anInstance have a zero reference counter, they'll be garbage collected?

• C# - What should I do when every inherited class needs getter from base class, but setter only for O

  - by msfanboy

  Hello, I have a abstract class called WizardViewModelBase. All my WizardXXXViewModel classes inherit from the base abstract class. The base has a property with a getter. Every sub class needs and overrides that string property as its the DisplayName of the ViewModel. Only ONE ViewModel called WizardTimeTableWeekViewModel needs a setter because I have to set wether the ViewModel is a timetable for week A or week B. Using 2 ViewModels like WizardTimeTableWeekAViewModel and WizardTimeTableWeekBViewModel would be redundant. I do not want to override the setter in all other classes as they do not need a setter. Can I somehow tell the sub class it needs not to override the setter? Or any other suggestion? With interfaces I would be free to use getter or setter but having many empty setter properties is not an option for me.

• An Inaccessible JavaScript Object property - Why is Firebug showing this?

  - by Matty

  So, I'm attempting to access the content of an object and for the life of me can't figure out why I can't. I'm starting to believe that the object doesn't have the properties that Firebug indicates that it does. More likely than that I'm just not using the right syntax to access them. Give the following function: function(userData) { console.log(userData); // statement 1 console.log(userData.t_nodecontent); // statement 2 } Which generates the following FireBug output for statement 1 and unknown for statement 2. Is there something obvious that I'm overlooking in the way I'm attempting to reference the value of t_nodecontent? I'm at a loss :(
